Application filed February 27, 1922. Serial No. 539,562.

To all whom it may concern:

Be it known that we, THoMAs rrLnX NDnR BOYD and HAROLD ARTHUR BOYD, subjects of, the King of the United Kingdomof Great Britain and Ireland, and residing at Shettleston, near Glasgow, Scotland, have invented a certain new and useful Improvement in Uop and Pirn lVinding Machines, of which the following is a specification.

Our invention refers to cop or pirn windber which is intermittently touched by the' yarn being wound on to the cop for the purpose of regulating the diameter of the cop). More particularly our invention refe'rsto improvements in "the construction of such feelers and means for operating the same and in windin' scribed.

Our invention comprises a'feeler which is rotated before the yarn'being wound upon the cop comes in contact with the feeler; it also comprises means for forming the bottom on such a cop by the action of a pusher shaft operating one or more feelers, and means for stopping individual winding spindles serving feelers on winding inachines of the kind described.

In the accompanying drawings F ig. 1 is an end sectional view of a machine embodying the invention. Figs. 2 and 3 are full size detail views of the frictional driver for the feeler. Fig. 4 is a detail View of the. pusher shaft for forming the cop bottom. shows a feeler with a detachable cone.

In a practical example of our invention embodied'in a machine for. winding fine cotton or silk yarn on to a paper tube to form a weft cop we employ a pair of spindle rails 1, 1 disposed parallel to one another and at the same level, located at a convenient dis tance apart, and extending from end to end of the machine. At right angles to the spindle rails 1, 1 at suitable distances apart we mount winding spindles 2 such as in bearings 3, 8. lVe shall describe in detail thearrangement and operation of one spindle.

, v Mounted on the spindle between the spindle rails 1, 1 is a wharve 8 which is driven by a g machines of the kind de- Fig. 5"

tape 4 coming from a tin roller 5 placed at a convenient distancs below and parallel with the spindle rails 1, 1. The tin roller 5, is carried on bearings and extends from end to'endof the machine and constitutes the main driver of the same. The spindle 2e21- tends to the front of the machine and placed on its outer end 2 is a paper tube 6 on which the yarn is to be wound. The spindle 2 extends behind the spindle rails 1, l and on its inner end 2 is a buckle 7 with a cross pin 8 at right angles to the spindle 2. Below the inner end of the spindle 2 we mount parallel with'the spindle rails l, 1, an oscillating traverse shaft 9. On the traverse shaft 9 below "the spindle buckle 7 we fix a wiper 10 which engages with the pin 8 in the buckle 7 and imparts to the spindle 2 a longitudinal traverse. Below the outer end 2 of the spindle 2 and parallel with it we mount a slide. rod

11 whose inner end 11 is supported on a bracket 12 fixed to the front spindle rail 1,

and whose outer end 11 extends to a suitable distance in a stay rail. 13 extending from end to end of the frame parallel with the said spindle rail 1. On the slide" rod 11. we mount a feeler slide 14 having a feather entering a key-way 11 on the upper side of'the slide rod 11. At the front end of the feeler slide 14: we form a projection 14 extending up- The conical end of the hole is of the shape of the yarn wound upon the cop, after the cop bottom is formed.

On the feeler 16 we form a boss 16 between the ball bearing and the apex of the conical hole in the feeler 16. Through the boss 16 we make a flattened hole 16'' into which we insert a frictional driver 17, Figs. 2 and 3.. The frictional driver 17 is made of wood with two layers of leather fixed on one side. We bore through the frictional 'driverl'? a hole 17 of diameter suitably larger than the diameter of the paper tube 6. Through the leather we form a hole 17 of less diameter than the paper tube. These holes in the driver are coaxial with the cop and spindle.

We make radial slits around the hole 17 in the leather to allow the paper tube 6 to be traversed longitudinally through the leather and with suflicient catch of the paper tube. 6 to be driven by it"when winding is p I v I p lever 25 extends to a point over the pulley proceeding.

On the feeler slide 14 we fix a thread guide 18 clear of the wide end of the cone. The yarn to be wound is drawn from a hank or other source and is guided on to the paper tube 6 which with the outer end of the pindle 2 has entered the feeler 16.

After the bottom of the cop has been formed as hereafter described, and while the winding is proceeding, the traverse of the spindle brings the yarnon the cone or; bottom of the cop against the conical hole of the feeler 16 and gradually forces the feeler 16 and the slide 14 away from the spindle 1 and cop or tube 6, thus locating the thread guide to form the cop. As thepaper tube 6 istraversed into the feeler 16', theffrid tion of the leather on the frictio na'ldriver 17 on the paper tube 6 rotates thefeeler 16 so that it is running approxi iately 'at.the speed of the cop ortube 6 w lien tlie yarn 'on the cop is pressed against the cohi'calhole'in thefeeler 16. i i

Formed on the outer end of the .feeler slide 14 belowthe slide rod is a d'ouble jaw 14 projecting downwa-rdsand open upto, the slide rod 14. In the double jaw -14 we mount a brake lever l8 carryinga weight 18 at its outer end andlat its inner end 18 a wood block 1.9, prejssingon'thelower side of the slide rod llffB'y this ineans suflicient resistance is given to the cop ,as it presses on the .feeler 14 to ensure a firml'y built cop. The pressure of the yarnbeing against a feeler which before the moment of touch is running at its own i'speed, there is no such rubbing of the 'yar'niias there would be if the feeler had to'be revolved by the pressure of the" yarn or if the feeler were stationary. i i

The spindle may be stopped automatically by the movement ofthe vf eler when the cop is filled, or by hand at will.

With this object in View, we mount on the framing a horizontal bar 203a about the same level as'the tin roller 5 and at a suitable distance behind the tin rollerl5f On the bar '20 we fix a bracket 21 on which we pivot a tension lever 22 extendingover the top of the tin roller 5 and carrying a ,tension pulley 23 resting on the upper side of the tape 4. By means o f this tension lever 22 and its pulley 23 the tape Lis tensioned to give sufficient drive for the spindle 2. To stop the spindle 2, we lift the tension lever 22 and pulley 23 off .thettape 4. For lifting the tension lever 22 we mount on the under side of the front spindle rail 1 in a bracket 24 a horizontal stop lever 25 located in the same vertical plane as the spindle 2. The stop lever 25 extends outwards and at its outer end 25 is a jointed catch lever 26 extending upwards and engaging a catch plate 27 .fixed upon the slide rod 11. The inner end 25 ofthe stop t ape 4 isslackened and the spindle 2 stops.

On the inner end 1 4 of the feeler slide 14 we fix a stop wire 29 extending inwards and bent behind-the catclnlever 26. This 'fst'op'wire 29 engages with and draws the catch lever 26 off the catch 27 when v the cop is. filled. vTo form a conical bottom of yarn l on the paper-lube 6 we mount on the framing parallel with the spindle rails '1 and below the ,feeler slide 14 a rotary pusher shaft 30. On thesaid pusher shaft 30pwe mount frictionally a pusher wiper 81which engageswith a' projection 14 onthe feeler slide 14. A stop 31 which extends horizontally below the slide .rod 11 limits 'thr-i'frangeof movement ofithe wiper with the shaft 30. The pushervshaft 30 is driven at reduced speed through gearing from the ,tin roller 5 and iscausedtorotate soithat ,the wiper .31 willpress the feeler 14 outwards at a slower speed than does the yarn whenthe cop is being built. Thus, when .startingftowind 011' a paper tub the feeler slide and thread guide are gradually pushed outwards until the yarn forms in cone shape on the tube, and the feeler slide being pressed ata slower speed thanrthe yarn builds at, ,the yarn gains upon andnltimately touches 'the feeler and pushes it outwards until the cop ,is fully formed. It willthus be under- ;stood that theya-rn coming from the .hank ,is wound on the paper tube which is traversed to and :fro past the thread guide, "first ,forming the cop bottomand thenpressing against the feeler and moving it and the thread guide outwards until the cop is fully formed. The feeler being rotatedbe- {fore ,the yarn on the cop comes in contact with it, ,the pressure of the yarn on the feeler causes no damage to the yarn. On completion of the cop the .feeler operates the stop motion andslackens the tape, there- ,by stopping the spindle. To permit quick alterations of the feeler to suit cops of varying diameter and shape, we make'the .feeler (Fig. 5) with a detachable conical end 32 which may, for example, be threaded into a support .3 3 carried by the ball bearing 15. I
